BACKGROUND

Coactivators are non-DNA binding proteins that mediate transcriptional activities of nuclear receptors (NRs) and many other transcription factors. More than 400 coactivators have been identified and associated with a wide range of human diseases, including neurological and metabolic disorders, inflammatory diseases, and cancer. Steroid receptor coactivators contain three family members, including SRC-1, SRC-2 and SRC-3, which function cooperatively to regulate many cellular signaling pathways. Taking estrogen receptor positive (ER+) breast cancer as an example, cancer cells can employ a number of mechanisms to overcome selective estrogen receptor modulators (SERMs) to silence the nuclear receptor (NR) activity. Although breast cancer cells can become resistant to endocrine therapies, it is essential for these cancer cells to recruit coactivators to survive. Coactivators also partner with other transcription factors; therefore, small molecule inhibitors (SMIs) that can directly target the overexpressed coactivators and reduce their activity or stability are targets for drug development. In addition, stimulation of coactivators can be beneficial for certain pathological conditions, including cancer, and can also be beneficial for the treatment of metabolic disorders.

II. Methods of Making the Compounds

The compounds described herein can be prepared in a variety of ways. The compounds can be synthesized using various synthetic methods. At least some of these methods are known in the art of synthetic organic chemistry. The compounds described herein can be prepared from readily available starting materials. Optimum reaction conditions can vary with the particular reactants or solvent used, but such conditions can be determined by one skilled in the art by routine optimization procedures.

Variations on Formula I, Formula II, Formula III, Formula IV, Formula V, Formula VI, Formula VII, Formula VIII, Formula IX, Formula X, Formula XI, Formula XII, Formula XIII, and Formula XIV, and tautomers thereof, include the addition, subtraction, or movement of the various constituents as described for each compound. Similarly, when one or more chiral centers are present in a molecule, all possible chiral variants are included. Additionally, compound synthesis can involve the protection and deprotection of various chemical groups. The use of protection and deprotection, and the selection of appropriate protecting groups can be determined by one skilled in the art. The chemistry of protecting groups can be found, for example, in Wuts, Greene's Protective Groups in Organic Synthesis, 5th. Ed., Wiley & Sons, 2014, which is incorporated herein by reference in its entirety.

The compounds described herein can optionally be isotopically substituted. For example, the compounds described herein can be substituted with stable or nonradioactive isotopes, such as deuterium, ¹³C, ¹⁵N, and/or ¹⁸O. Incorporation of a heavy atom, such as substitution of deuterium for hydrogen, can give rise to an isotope effect that could alter the pharmacokinetics of the drug. In some examples, at least 5 mol % (e.g., at least 10 mol % or at least 25 mol %) of an atom (e.g., a hydrogen, carbon, nitrogen, or oxygen atom) in a compound described herein is substituted with a stable isotope. For example, at least 50 mol %, 60 mol %, 70 mol %, 80 mol %, or 90 mol % of an atom in a compound as described herein can be substituted with a stable isotope. Isotopic substitution or enrichment can be achieved, for example, by exchanging protons with deuterium or by synthesizing the molecule with enriched or substituted starting materials. Other methods known in the art can also be used for isotopic substitutions.

Reactions to produce the compounds described herein can be carried out in solvents, which can be selected by one of skill in the art of organic synthesis. Solvents can be substantially nonreactive with the starting materials (reactants), the intermediates, or products under the conditions at which the reactions are carried out, i.e., temperature and pressure. Reactions can be carried out in one solvent or a mixture of more than one solvent. Product or intermediate formation can be monitored according to any suitable method known in the art. For example, product formation can be monitored by spectroscopic means, such as nuclear magnetic resonance spectroscopy (e.g., ¹H or ¹³C) infrared spectroscopy, spectrophotometry (e.g., UV-visible), or mass spectrometry, or by chromatography such as high performance liquid chromatography (HPLC) or thin layer chromatography.

SI Compounds Regulate Intrinsic Transcriptional Activities of SRCs

The effects of the SI compounds described herein on the intrinsic transcriptional activities of SRC-1, SRC-2 and SRC-3 were investigated. HeLa cells were transiently transfected with a pGL5-LUC reporter and expression vectors for pBIND and pBIND-SRC-1, pBIND-SRC-2, pBIND-SRC-3, followed by 24 hours of treatment with different concentrations of SI compounds. Compounds as described herein, including SI-9, SI-10, SI-11, SI-12, SI-14, SI-15, SI-16, SI-17, SI-19, SI-20, and SI-21, were tested for their ability to inhibit the intrinsic transcriptional activity of SRC-1, SRC-2 and SRC-3 in FIG. 1. Some compounds, including SI-3, SI-4, SI-5, SI-6, SI-7, and SI-8, were able to stimulate SRC-3 intrinsic activity at certain doses (FIG. 2).

Example 3

SI-12 was tested in pancreatic, lung, brain, and melanoma cancers. A representative example for pancreatic tumor treatment is described below. Panc-1 cells stably expressing firefly luciferase cells (Panc-1-Luc, 0.5×10⁶ cells per mouse) were injected into the tail of pancreas of SCID mice (6-7 weeks). The mice were randomized into two groups based on luciferase imaging (n=8 per group). Eight days after tumor inoculation, the two groups were administered SI-12 (10 mg/kg, i.p. injection, once daily) or an equal volume of vehicle control five times per week. Tumor growth and systemic toxicity were monitored based on luciferase imaging and body weight weekly. The mice were sacrificed after eight weeks of treatment. SI-12 treatment significantly delayed pancreatic tumor growth (FIGS. 3A and 3C), while causing minimal body weight loss (FIG. 3B). At the end of the experiment, tumors were harvested and weighed. The average tumor weight in SI-12 treated mice was ˜30% of the vehicle treated counterparts (FIG. 3D).

To test whether SI-12 causes SRC-3 down-regulation in vivo, the SRC-3 levels in tumor tissues were measured by immunohistochemistry (IHC). Multiple tumor tissues (N>3) collected from both the control group and the SI-12 treated group were processed and immunohistochemically stained with an anti-SRC-3 antibody or an anti-Ki-67 antibody. As shown in FIG. 3E, the SRC-3 levels (dark color) in SI-12 treated tumor tissues were significantly lower than the vehicle treated control group. Ki-67, a cell proliferation marker, was also immunochemically analyzed. The SI-12 treated tumor tissues had dramatically fewer Ki-67 positive cells (the cells with dark staining, FIG. 3E). Based on these data, SI-12 significantly inhibits pancreatic tumor growth through inhibition of SRC-3.

SI-12 was also tested for its ability to disrupt kinase activity. The effects of the compound were tested on a panel of 24 kinases using a Kinase-Glo Luminescent Kinase Assay system (Promega; Madison, WI). SI-12 was tested, at concentrations of 1000 nM, 50 nM, and 5 nM, for its ability to interfere with recombinant kinases in the assay system. The amount of ATP to ADP conversion in the presence of SI-12 was compared to a DMSO vehicle control. The values shown in Table 3 represent the percentage of kinase activity compared to a DMSO vehicle control. SI-12 had minimal effects on kinase activity in this biochemical assay system (see Table 3).

FIG. 4 shows that SI-12 can inhibit tumor growth in a MDA-MB-231 xenograft model. SI-12 was evaluated in a MDA-MB-231 model where the MDA-MB-231 tumor cells were stably transfected with a luciferase expression vector. Nude mice had 2.5×10⁵ tumor cells implanted into cleared mammary fat pads of nude mice. The progression of tumors in control and SI-12 treated animals (4 mg/kg 5 times per week) was followed by luciferase imaging of the mice over a five-week period. It was shown through whole body luciferase imaging that SI-12 reduced luciferase expression at both the sites of the primary tumor and of MDA-MB-231 metastasis to the lung (FIG. 4).
